Police are on alert in case of a backlash after Channel 4 airs a documentary featuring the UK's first gay Muslim drag queen.

Asif Quaraishi, an activist for the so-called "Gaysian" community who performs in clubs as the glamorous Asifa Lahore, has received death threats in the past and is concerned about the public reaction to Muslim Drag Queens when it airs on Monday night.

"I do worry post the broadcast," said Quaraishi, who added that authorities and police have been notified about the broadcast next Monday. "There are certain things that have been put in place for my safety. The death threats featured [in the doc] were last year. As and when those things happen the police are always informed and they have been ridiculously supportive."
